After receiving a fun little shock, I found that someone was using 14/3 cabling to carry 2 different circuits to this 1 gang box (line on left, load on right). Since the load for Circuit 2 doesn't have a matching neutral, it's . In fact, you could use a divider in your box between the three lighting controls and the two receptacle devices; you'd then need grounding pigtails in both compartments, but it would make it much easier to keep your .The answer is yes you can have 2 separate circuits in the same box (they can have a splice also but not needed in your case). The only concern would be the total box fill. Based on the NEC the wire fill would be calculated at 2.0 for each . But either just two circuits or even two voltages in dual gang box is allowed and is common. If you have two circuits (not an MWBC) on a duplex receptacle you need to break off .
Assuming the junction box has the proper capacity, I want to run a separate circuit through that box so as to split-off a circuit which will then go two different ways to power up an outlet on .
Just one circuit, but two different hot runs in the same junction box. So: hot from junction box to 3-way switch (12/3 to second switch and third wire to lights.) This third wire will .You can save time and money by using a single junction box to accommodate two different circuits. If you want to hire an electrician, you can also reduce labor costs by cutting down on the number of junction boxes they have to install.
2 circuits in one ceiling box. If you have only a white and black at the switch, it is usually because it is fed hot by a piece of 2-wire BX cable. One wire is the hot and the other is . Can two different circuits go through the same junction box? That is, two cables enter from different breakers and they tie to cables exiting, but the two circuits aren't . Electrical - AC & DC - 2 circuits. 1 Junction box. OK? - Hello all. Is there any prohibition against power from two separate circuits entering one switchbox? Specifically, I want to have a switch that controls a dining room light to be in the same switchbox as a switch that controls a living room light. Power from I have a couple of bathrooms that have 277v lighting and 120 volt fans that the print shows to be controlled by one switch. The Accuity brand switch, occupancy censor switch Model ( WSM-PDT-D-WH ) I was not aware that you could mix circuits from one panel that is 480 / 277 with another one that is 120 /208.

I then have a METAL double gang outlet box that contains some splices.. inside this box is a junction that ties 3 of the main panel 20 amp 12 AWG wires together on an outlet branch and no devices. The #12 is THHN fed via PVC not EMT to the box. . I need to add a 3-way switch into this box (part of a 4-way circuit) that is on a 15amp branch . Well, you can run two totally separate circuits to the box, from two toally separate single-pole breakers. That way if one trips, the other does not. Nothing wrong with that. You can also run a "Multi Wire Branch Circuit" (MWBC) from a two-pole breaker (a fault on either will shut both down) with a single neutral and two hots.I recently purchased an older house and in doing renovations have run into a situation where two circuits (wired with 14/2) are present in one junction box and all neutrals are tied together. I understand that this was an accepted practice at some point but no longer code compliant for obvious reasons.
converting two lights from two switches to two lights from one switch. 3. . Two circuits in same junction box when each circuits originates from two different subpanels. 5. How to wire two different 3-way circuits from same box. 1. Can different wire gauges be combined in same box? Hot Network QuestionsUsing one junction box for multiple circuits saves space. However, multiple junction boxes make more sense. You have two significant issues: 1). Safety. First of all, sharing a box between multiple circuits is risky. You are more likely to damage the wires, especially when the junction box is too small. Crowding bends the conductors, which . You can have multiple circuits in one box. But you have to: Keep all matching hots, switched hots and neutrals of any circuit together; . and disconnect the wires at the breaker or prior junction so that you don't have extra, unknown, live wires in the box. Combining Circuits.This is most likely a multi wire branch circuit (very common). The neutral is shared in the 12/3. As long as the red and black are on opposite phases, the neutral will only carry the difference in current between the two hots. At this junction box the multi wire branch circuit splits into 2 .
Is it in the kitchen? there are many instances when you have more then 2 circuits in one box. for example if you have 3 sets of lights and each set requires dedicated circuit and all 3 switches are in the same box, you will have 3 breakers ( circuits going to the box ). although in multi wire systems ( black, red, white) code states that if both circuits are feeding one device on the .
250.148 Continuity and Attachment of Equipment Grounding Conductors to Boxes. Where circuit conductors are spliced within a box, or terminated on equipment within or supported by a box, any equipment grounding conductor(s) associated with those circuit conductors shall be connected within the box or to the box with devices suitable for the use in accordance with 250.148(A) .
In the attached file I have two different Receptacles, one with "Shared" and two nested extrusions, the other is simply a single receptacle with 2 connectors tied to both sides. If you look at the circuits, both connectors are on a different circuit like I would expect, but I can't list the circuit number for the secondary connectors in a label. I have a two gang device box with one single pole switch (circuit#1) & one GFI receptacle (circuit#2). Do I need to put a box partition to separate the two. Menu. Home. . 2-120v circuits in same junction box. Thread starter Coastalguy1; Start date Feb 1, 2012; Status Not open for further replies. Coastalguy1 Member. Location Virginia Beach, VA.

I have a double gang junction box which will house two switches, one controlling main lights which are at 277V and the other controlling decorative lighting at 120V. I know NEC 300.3 (C) (1) says that they can occupy the same enclosure, but do I need to add any kind of identification to the. Electrical - AC & DC - Two circuits in 2-gang box? - I'm planning a kitchen remodel for my brother. . do not connect neutrals together in the junction box. All ground wires get spliced. In this case, handle tie is not required. . the breakers will have a handle tie. The possibility of having one dead and one hot circuit in the same box just . You have 10 "conductors" at 12 AWG = 10 x 2.25 = 22.5 cu in. You have 5 "equipment grounding conductors" = 1.25 x 2.25 = 2.8 cu in. Assuming you have internal cable clamps = 2.3 cu in. Assuming no other device or .

Im passing 2 circuits and a ground from LB to junction for backyard outside circuits. So two neutral, two hot, and one ground 10 awg. The LB box screw fell into the vertical pvc conduit last minute, and I have a few feet of wire pulled out of LB. I tried getting it but cannot. I would rather not pull the wire anymore to not damage it. Just one circuit, but two different hot runs in the same junction box. So: hot from junction box to 3-way switch (12/3 to second switch and third wire to lights.) This third wire will come back through the junction box where the hot originated from, . The switches exist, because it is allowed. The number of circuits is not the problem. It is common to have 2, 4 or even 6 switches. But multiple phases going into the same switch box can be an issue in some jurisdictions. Again, danger wise, multiple circuits is fine, but not multiple phases, which could substantially increase the voltage.
Two circuits can share a box, and even serve different switches or outlets in the same box. Be careful to keep hots and neutrals separate. For instance a household member really likes running the hair dryer and curler at the same time. I have two separate 3-way lights that need to be powered from the same power source in one box (in addition to using the box as a junction to supply power to a different box, but I can't see why that . . Two circuits in same junction box when each circuits originates from two different subpanels. 1. Can different wire gauges be combined in .So there may be a 2 gang junction box containing switches and receptacles on separate circuits. Another example in the kitchen. Code requires a minimum of 2 small appliance branch circuits serving kitchen countertops. Back in the day before code changed we used to pull a 12/3 to one box, then branch off both directions.The problem is that 2 circuits are running through this outlet. You will notice in the diagram below, that all of the Whites (Neutral) are capped off with each other and connect to the outlet once, while two hots come off the outlet. The wiring in the upper .
As an electrician, you can suspect a multi-wire branch circuit when three or more neutral conductors are spliced together in a junction box, outlet box, or lighting fixture. Can you run two circuits one outlet? It’s possible to safely have two circuits feeding one receptacle, if you have a hot/neutral pair for each segment. Additionally . Conductors of circuits rated 600 volts, nominal, or less, ac circuits, and dc circuits shall be permitted to occupy the same equipment wiring enclosure, cable, or raceway. All conductors shall have an insulation rating equal to at least the maximum circuit voltage applied to any conductor within the enclosure, cable, or raceway.

Each lamp has its own dimmer switch in the same junction box. It is very tight/crowded in the box. I cannot tighten the switches without them being misaligned. I cannot get the switch cover onto the switch box. . Great solution as long as the 2 lights are on one circuit, which is most likely the case but not guaranteed. – manassehkatz . If I want to connect a second wire to come from that junction box, would I just attach all hot and all neutral wires together in the box? In my head it sounds like this wouldn't be a complete loop, but maybe I am just overthinking it. So one source going into the box and then two wires coming out of it, each going to their own box in the walls .
